Abstract
Description
Technical Field
[0001] This invention relates to the field of communication equipment, and more specifically to an electromagnetic interference resistant network switch. Background Technology
[0002] A network switch is a communication device that can expand a network by providing more connection ports for subnets to connect more computers. With the development of the communications industry and the advancement of national economic informatization, the network switch market is also showing an upward trend. It has the characteristics of high cost performance, relative simplicity, and ease of implementation.
[0003] However, when network switches are connected by network cables, the transmission of electrical signals often generates electromagnetic interference, which can affect the normal operation of other systems or other subsystems within the same system.
[0004] For example, when an Ethernet cable passes through a magnetic field, a current is generated in the cable, which distorts the Ethernet signal and impairs the integrity of data packets, potentially leading to intermittent communication. Therefore, the national standard proposes MICE requirements for Ethernet cabling systems in industry, namely Mechanical Environment, Entry Point, Temperature and Humidity, Electromagnetic Interference and Electrostatic Discharge, to ensure data integrity during network transmission.
[0005] In existing technologies, network switches are often designed with a focus on one or more aspects, such as the mechanical structure itself or electromagnetic interference resistance, while other aspects cannot be taken into account. This leads to an increased possibility of external damage to network switches during operation, and the inability to guarantee electromagnetic interference resistance. Consequently, the possibility of packet loss during transmission increases, affecting the transmission efficiency of Ethernet. Summary of the Invention
[0006] To address the aforementioned problems, this invention provides an electromagnetic interference-resistant network switch, which solves the problem that traditional network switches cannot simultaneously provide mechanical damage protection, chemical damage protection, and electromagnetic interference resistance.
[0007] The technical solution adopted in this invention is: an anti-electromagnetic interference network switch, comprising a housing and a switch body;
[0008] The housing includes side plates, a bottom plate, a front connecting plate, and a rear connecting plate;
[0009] The upper end of the housing is provided with a cover plate, which is connected to the side plate by a snap fastener.
[0010] The side panels are all equipped with a honeycomb heat dissipation structure. The front connecting plate has several RJ35 interfaces embedded in it, and the rear connecting plate has an AUI interface and several Console interfaces embedded on one side of its outer side, and several heat dissipation vents running through it on the other side.
[0011] The RJ35 interface is equipped with a dustproof plate at the inner opening on the outer side. The dustproof plate is connected to the front connecting plate by a spring to prevent dust or liquid from entering the interface.
[0012] The housing is also provided with a number of conductive foams, which are strip-shaped and are respectively located at the connection between the cover plate and the housing, the connection between the side plate and the front connecting plate and the rear connecting plate, and the connection between the side plate and the bottom plate.
[0013] Several thermal pads are also fixedly provided on the upper end of the base plate, and the thermal pads are bonded to the base plate.
[0014] Furthermore, the front of the cover plate is provided with a downward folding baffle, and the cover plate and the housing are connected by buckles located at the lower ends of both sides of the cover plate and slots on the upper end of the side plate that match the buckles.
[0015] Furthermore, each interface on the front connection board is equipped with an indicator light at its upper angle to display the current working status of each interface.
[0016] Furthermore, a dustproof mesh is attached to the inside of the side panel to prevent dust and insects from entering the switch.
[0017] Furthermore, rubber pads are fixed at the four corners of the bottom of the base plate, and the base plate is also provided with several through holes for fixing the switch to a vertical structure such as a wall with screws.
[0018] Furthermore, the thermal pad is made of silicone, and the thermal pad is bonded to the base plate with high-temperature thermal paste.
[0019] Advantages of this invention:
[0020] This invention combines the characteristics of network switches such as mechanical damage prevention, waterproofing and dustproofing, electromagnetic interference resistance, and electrostatic discharge resistance, ensuring the normal operation of the switch. In terms of facilities, rubber pads and shock absorption devices reduce mechanical damage to the switch, and the spring-loaded device at the plug ensures that the plug is waterproof and dustproof when not in use. The heat dissipation effect is improved by the honeycomb-shaped heat dissipation holes on the side, the heat dissipation holes at the rear, and the thermal pad at the bottom. By setting conductive foam inside the switch housing, shock absorption and electromagnetic interference resistance are provided, enhancing the switch's anti-interference ability and preventing damage to the switch caused by mechanical activities, dust and liquid splashes, or temperature and humidity changes.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] refer to Figures 1 to 7 An electromagnetic interference resistant network switch, comprising a housing and a switch body;
[0043] The housing 1 includes a side plate 11, a bottom plate 12, a front connecting plate 13, and a rear connecting plate 14;
[0044] refer to Figures 3 to 4 The upper end of the housing 1 is provided with a cover plate 2. The cover plate 2 is connected to the side plate 11 by a buckle 211. It should be noted that when it is necessary to remove the cover plate 2 to insert the switch body into the housing 1, press the upper end of the cover plate 2 and slide it forward. Due to the presence of the buckle 211, the cover plate 2 can slide relative to the side plate 11, thereby completing the removal of the cover plate 2.
[0045] refer to Figures 5 to 7 The side plates 11 are all provided with honeycomb heat dissipation structures 111, the front connecting plate 13 is embedded with several RJ35 interfaces, the rear connecting plate 14 is embedded with an AUI interface and several Console interfaces on one side, and several heat dissipation vents 141 are provided through the other side.
[0046] refer to Figure 6 The RJ35 interface has a dustproof plate 131 at the inner opening on the outer side. The dustproof plate 131 is connected to the front connecting plate 13 by a spring to prevent dust or liquid from entering the interface. It should be noted that when the plug needs to be inserted into the interface, it can be inserted forward. The dustproof plate 131 at the interface can squeeze the spring and fall forward. When the plug is pulled out, the dustproof plate 131 returns to its original position under the reaction force of the spring to prevent dust or liquid from entering the interface.
[0047] refer to Figure 8 The housing 1 is also provided with a plurality of conductive foams 3. The conductive foams 3 are strip-shaped and are respectively provided at the connection between the cover plate 2 and the housing 1, the connection between the side plate 11 and the front connecting plate 13 and the rear connecting plate 14, and the connection between the side plate 11 and the bottom plate 12.
[0048] refer to Figure 2 The upper end of the base plate 12 is also fixed with a plurality of heat-conducting pads 4, which are bonded to the base plate 12.
[0049] The front of the cover plate 2 is provided with a downward folding baffle 21. The cover plate 2 and the housing 1 are connected by buckles 211 located at the lower ends of both sides of the cover plate 2 and a slot 112 on the upper end of the side plate 11 that matches the buckles 211. The function of the baffle 21 is to prevent the cover plate 2 from slipping when it is inserted into the housing 1.
[0050] refer to Figure 1 Each interface on the front connection plate 13 is also provided with an indicator light 132 at its upper diagonal end, which is used to display the current working status of each interface. It should be noted that the power supply of the indicator light 132 comes from the power supply of the switch.
[0051] The side panel 11 is fitted with a dustproof net 113 to prevent dust and insects from entering the switch.
[0052] refer to Figures 5 to 8 The bottom of the base plate 12 is fixed with rubber pads 121 at the four corners. The base plate 12 is also provided with several through holes 122 for fixing the switch to a vertical structure such as a wall with screws. It should be noted that the through holes 122 are larger at the top and smaller at the bottom. When the screw is inserted into the through hole 122, the screw head will be stuck due to the structure of the through hole 122. At this time, the screw head is parallel to the upper end of the base plate 12, preventing the screw from directly contacting the switch body and thus damaging the switch body.
[0053] The thermal pad 4 is made of silicone. The thermal pad 4 is bonded to the base plate 12 with high-temperature thermal paste. The thermally conductive silicone uses silicone as the base material and adds various auxiliary materials such as metal oxides. It is synthesized through a special process and has both processability and practicality. It can fill gaps and complete the heat transfer between the heat-generating and heat-dissipating parts. At the same time, it also plays a role in insulation and shock absorption.
[0054] This invention provides an electromagnetic interference-resistant network switch, comprising a housing for mounting the switch body and a closed cover. The housing is equipped with a switching port, a heat dissipation structure, a waterproof, dustproof, and insect-proof structure, an electromagnetic interference-resistant structure, and a mechanical anti-collision and anti-damage structure. It can resist electromagnetic interference while satisfying mechanical damage and collision protection, preventing the switching speed of the network switch from being affected by excessive temperature and humidity, thereby increasing the data packet loss rate, and preventing mosquitoes, dust, and liquids from entering the switch body and causing short circuits in the switch.
[0055] This invention can protect the switch and ensure its normal operation. It provides mechanical shock absorption for the switch through the rubber pad at the bottom of the base plate and the thermal pad at the top of the base plate. Heat transfer is completed through the honeycomb heat dissipation holes on the side plate, the heat dissipation holes on the rear connecting plate, and the thermal pad at the bottom, which improves the heat dissipation effect. The conductive foam placed at the corners of the connection points inside the housing can resist electromagnetic interference. The dustproof net and dustproof plate prevent dust and liquid from entering the switch.
[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
